NOTE D—CONCENTRATION OF RISK
 
Financial instruments which potentially subject the Company to risk primarily consist of cash and accounts receivables.
 
The Company maintains its cash and cash equivalents with various financial institutions, which, at times may exceed the amounts insured by the Federal Deposit Insurance Corporation. The exposure to the Company is solely dependent upon daily bank balances and the respective strength of the financial institutions. The Company has not incurred any losses on these accounts. At December 31, 2015 and 2014, amounts in excess of insured limits were approximately $4,073,000 and $586,000, respectively.
 
The Company extends credit to customers on an unsecured basis in the normal course of business. The Company’s policy is to perform an analysis of the recoverability of its receivables at the end of each reporting period and to establish allowances where appropriate. The Company analyzes historical bad debts and contract losses, customer concentrations, and customer credit-worthiness when evaluating the adequacy of the allowances.
   
The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, as follows:

Customer A’s receivable of $2,070,000 has been past due per the terms of the invoice for six months as of December 31, 2015. Based on prior history with this customer the Company feels the amount is fully collectable and has determined that a reserve is not necessary.
